Airtac SAIF Series Standard Cylinder with Valve SAIF63X75-08A
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF63X75-08A is a genuine double-acting ISO 15552 cylinder with a Ø63mm bore, 75mm stroke and a built-in 4M310-08 5/2 solenoid valve — it switches itself from one coil signal, so no separate remote valve or extra plumbing is needed.

About the Airtac SAIF Series Standard Cylinder with Valve SAIF63X75-08A
The AirTAC SAIF63X75-08A is a double-acting ISO 15552 profile cylinder featuring an integrated 4M310-08 5/2 solenoid valve. This built-in valve provides a Cv of 1.40 and routes air directly through a manifold block using PU tubing, eliminating the need for separate remote valves and extensive plumbing. Driven by an AC220V terminal-type coil consuming 3.5 VA, the unit responds in 0.05s and carries an IP65 rating. Because the valve operates at 0.15-0.8 MPa, this defines the practical working pressure for the assembled SAIF unit, even though the bare cylinder itself rates to 1.0 MPa.
In its factory setting, the piston rod retracts when the coil is energised, but you can reposition the valve to extend-when-energised if your logic requires it. The 63mm bore generates 1559N of push force and 1402N of pull force at 0.5 MPa, making it suited for mid-weight handling tasks. The cylinder port is 3/8 inch, while the valve features a 1/4 inch port, and the assembly uses standard carbon steel piston rod material.

The cylinder rates to 1.0 MPa but the built-in valve operates 0.15–0.8 MPa, so run the assembled SAIF at 0.15–0.8 MPa. Default: rod retracts when the coil is energised (reconfigurable to extend). Specs follow the official AirTAC SAIF datasheet. Port options: PT / G.
Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
Sized within the valve's 0.15–0.8 MPa range. Actual usable force is lower than theoretical due to friction and back-pressure.

SAIF does not hold its load without air — the valve routes air, it is not a lock. For load-holding use a SAIL (lock) or BSAI (clamp-lock).
Where the Airtac SAIF Series Standard Cylinder with Valve SAIF63X75-08A Is Used
Decentralized Assembly Lines
Perfect for large machines with multiple stations, using the built-in valve to cut down on panel space and centralized plumbing.
Mid-Force Material Handling
Provides 1559N of push force at 0.5 MPa to lift and transfer heavier workpieces on conveyors without needing a remote valve bank.
Space-Constrained Retrofits
Ideal for upgrading older machines where adding external pneumatic tubing is difficult, as the 4M310 valve switches the cylinder directly.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF63X75-08A the Right Choice?
Choose this 63mm bore when a 50mm bore (delivering 982N push at 0.5 MPa) is too weak, but an 80mm bore (2513N push) is oversized. The self-valved SAIF design excels in decentralized machine stations where running separate valve tubing is costly or space-prohibitive. When ordering replacements, confirm the 75mm stroke, the 4M310-08 valve port, the AC220V voltage, the terminal electrical entry, and the PT thread type. Note that this configuration does not include a magnet (-S), so it will not trigger reed or electronic sensors without modification.
Because the 5/2 valve only routes air and the end cushions merely decelerate the load near stroke end, this cylinder does not hold its position without live pressure. For true load-holding requirements, consider the SAIL lock variant instead.
Quick checklist
- ✓ Force at 0.15–0.8 MPa
- ✓ Coil voltage matches panel
- ✓ Terminal vs grommet entry
- ✓ Retract- or extend-when-energised
- ✓ Load-holding → SAIL / BSAI
Airtac SAIF Series Standard Cylinder with Valve SAIF63X75-08A FAQ
The 63mm bore generates 1559N push and 1402N pull force at 0.5 MPa. The integrated 4M310-08 valve has a 25.0 mm2 orifice with a Cv of 1.40.
The built-in 5/2 valve allows the cylinder to switch itself from a single AC220V coil signal, saving space and tubing. By default, the rod retracts when energised, but you can reposition the valve to extend-when-energised.
